A cyclin called cyclin E forms a complex with a cyclin-dependent kinase called Cdk 2. This complex is important for the progress

ion of the cell from G1 into the S phase of the cell cycle. Which of the following statements is most likely to be correct? A. The amount of Cdk 2 is greatest during G1. B. The amount of unbound cyclin E is lowest as the cell enters S. C. The activity of the cyclin E/Cdk 2 complex is highest during G2. D. The amount of unbound cyclin E is greatest during the S phase. E. The amount of Cdk 2 is greater during G1 compared to the S phase.

Answer:

B. The amount of unbound cyclin E is lowest as the cell enters S.

Explanation:

The reproduction of the cell is a cycle that it regulates by itself, depending the  demand of a certain cell.

In the case of the mitosis, in Each change from G1 to S to G2 to M is regulated by some proteins like the cyclin.

In the case of the cdK2 is ncessary to pass the control point to pass from the stage G1 to the stage S.

Another characteristic of the cyclins, is that these proteins are synthetized and degraded constantly during the hole process.

Hope this is a useful info

Bingel [31]

Complete question:

You hang a swing from a live tree branch that is roughly parallel to the ground. What will likely happen over time as the tree grows? Check All That Apply

  1. The swing will move farther away from the tree trunk.
  2. The swing will move up. away from the ground.
  3. The swing will remain in its original position.
  4. The swing's ropes will become embedded in the branch.

Answer:

The swing's ropes will become embedded in the branch.

Explanation:

The trunk or branch strangulation sadly occurs very often. When people tie a young tree with different materials, such as a rope, or a cable, or a wire, and leave it there, the leash will eventually strangulate the tree.

Strangulation occurs because the tree keeps growing, applying pressure on the leash. The vascular system is in the trunk perimeter under the crust. Through the years, the pressure increases, the trunk is even more strangulated, and the vascular system is affected. One of the first and principal effects of strangulation is the increase in the trunk or branch diameter over the leash. This diameter change is because elements of the sap can not go back to the roots and keep near the strangulation. At this point, there are two options:

  • The tree can sort this by including the leash in its tissues, surrounding and absorbing it, and keep growing normally

or

  • The vascular system is so affected that the tree can not sort this problem and so, those parts of the tree located over the leash dye.

<em>In the exposed example, it seems that the tree could make it and included the swing's ropes in the branch. </em>

Which of the following are considered rocks?
kipiarov [429]

Answer:

1-A: - Granite

2-E: - Boulder

Explanation:

- Granite is a light-colored plutonic rock found throughout the continental crust, most commonly in mountainous areas.

˜”*°•.•°*”˜˜”*°•.•°*”˜˜”*°•.•°*”˜˜”*°•.•°*”˜˜”*°•.•°*”˜˜”*°•.•°*”˜

- The difference between a rock and a boulder can be explained in terms of size and detachment. A rock is defined by geologists as an aggregate of minerals. A boulder is a type of rock, specifically a large detached one. All boulders are rocks, but not all rocks are boulders.

˜”*°•.•°*”˜˜”*°•.•°*”˜˜”*°•.•°*”˜˜”*°•.•°*”˜˜”*°•.•°*”˜˜”*°•.•°*”˜

I'm sorry if this is wrong but after doing some research for this I only found that granite and large boulders are considered rocks. And again I'm sorry if this is wrong, and sorry that this response is late.,.

Edit: Can you tell me if the answers is wrong? you don't have to tho.
